My song of choice is "Born to die" by Lana del Rey.
I usually start Mondays in good spirits first thing in the morning, since I have no trouble getting out of bed. However, as the hours go by at the office, I find that the day gets heavier and heavier and when I get home after a Monday at work I am metaphorically dead.
That's why the title of this song fits my Mondays where I am born very happy and strong, but I get home dead.
